MANURE-SORAPER.

To all whom it may concern:

Be it known that we, CORNELIUS DIELE- MAN, l/VIEGERT D. RIETVELD, and JOHN D. PtrE'rvELn, citizens of the United States, residing at Pella, in the county of Marion and State of Iowa, have invented a certain new and useful Manure-Scraper, of which the following is a specification.

The object of our invention is to provide a wheeled scraper of simple, durable and inexpensive construction, designed to be ad vanced by draft animals, and so arranged that it will scrape up manure or other ma terial resting upon the ground surface and conduct it to a point of discharge.

A further object is to provide simple and easily operated means whereby the operator may either hold the scraper blade to the ground or elevate it above the ground as may be desired.

A further object is to provide means whereby the two draft animals that are ordinarily used for advancing the scraper may be made to advance on opposite sides of the scraper or may be made to advance directly in front of the scraper, so that the sides of the scraper may be advanced close to a fence or other obstruction.

More specifically, it is our object to provide an improved double tongue for devices of this kind in which the portions of the tongue may be supported at opposite sides of the device and each be designed to have a draft animal attached to it, or the two portions of the tongue may be brought together in front of the center of the device and the draft animals attached to it in the same manner as they would be to a single vehicle tongue.

Our invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of a device embodying our invention with the scraper blade in its lowered position and the tongue sections attached to the outer sides of the scraper. Fig. 2 is a top or plan view of same. Fig. 8 shows a rear end elevation, on an enlarged scale of the foot lever device for raising and lowering the scraper blade. Fig. 4 shows a top or plan view of the pivoted swingle-tree. Fig. 5 shows a sec- Specification of Letters Patent.

tional view of same looking toward the Fig. 6 shows a side elevation of the complete device embodying our invention with the scraper blade in its elevated position and the tongue sections brought together and secured to the center of the device. Fig. 7 is a top or plan view of same. Fig. 8 shows an enlarged, detail sectional view illustrating the means for supporting the swingle-three holding arm when at its inward limit of movement, and-Fig. 9 shows a detail view illustrating the means for supporting the swingle-tree holding arm when at its outer limit of movement.

Referring to the accompanying drawings, we have used the reference numeral 10 to indicate the supporting axle upon which the wheels 11 are mounted. This axle is passed through the side-boards 12, the forward portions of which have their lower ends arranged so that they may rest flat upon the ground'surface over which the wheels are traveling, and the rear ends are inclined upwardly and rearwardly. At about the central portion of the side boards 12, is a scraper blade 13 extended vertically and fixed to the side-boards.

Extended rearwardly from the axle 10 is a V-shaped frame 14 having an axle wheel 15 at its rear end for supporting it, and above the axle wheel is a drivers seat 16.

Fixed to the central portion of the scraper blade 13 are two parallel uprights 17 and pivoted between them is a bar 18 extended rearwardly and downwardly and provided with a loop 19 at its rear end.

Supported between the sides of the frame 1 1 is a bar 20 having pivoted to it a sub stantially U-shaped lever 21 provided with two treadles 22 and 23, the latter treadle having the loop 19 attached to it. By this arrangement it is obvious that when the operator presses forwardly upon the treadle 23, the side-boards 12 will be moved to position with their lower ends parallel with the ground surface as shown in Fig. 1, and when the operator presses downwardly upon the treadle 21, the side-boards are tilted upwardly as shown in Fig. 6.

In order to counter-balance the weight of the forward end of the scraper, we provide a contractible coil sprin 24 attached to one of the uprights 17 and extended rearwardly and downwardly and attached to the frame 20, the said spring being of such resilience that when the side-boards 12 are tilted to the position shown in Fig. 6, it will maintain them in said position until the treadle 23 is moved forwardly by the operator.

Mounted upon the sideboards 12, is a cross piece 25 in front of and above the axle 10, and above this cross piece is a rod 26 supported by the braces 27. This rod is for the purpose of support-ing the tongues. Ordinarily, we prefer to use an independent tongue for each draft animal, which tongue extends forwardly and outwardly from the runner. Each tongue comprises a straight body portion 28 having a loop 29 at its rear end, mounted upon the rod 26, said loop being pivotally mounted on the tongue. Fixed to the rear portion of the tongue is a brace 30 extended rearwardly and inwardly and having a forked rear end to encircle the central portion of the rod 26. A bolt 31 is pro vided for connecting the forked end with the rod 26, and a pin 32 is passed through the rod 26 to limit the inward movement of the loop 29 on the rod. In this way, each tongue is firmly and securely held in a position inclined forwardly and outwardly from the runner. Pivoted to the forward portion of the tongue is an arm 33 extended outwardly and held in position by means of a chain 34, which chain is detachably connected with the forward end of the tongue.

In some instances it is desirable to provide for advancing the machine by means of a tongue in the center of the machine, and when this is done, we remove the bolts 31 from both braces and also the pins 32. We then slide the loops 29 toward the center of the rod 26 as shown in Fig. 7, the braces 30 will then project upwardly and rearwardly. In order to hold the rear ends of the tongues together, we provide two rods 35 having hooks at their ends to over-lap the braces 30. The arms 33 at the forward ends of the tongues are then moved rearwardly and the chains 34 are detached from the front of the tongue and connected with the hooks 36 on the tongues.

When the tongues are used at the ends of the scraper blade, it is necessary to have an arm projecting out from the scraper for attaching a swingle-tree, and when the tongues are at the center, it is necessary to have a swingle tree supported between the sideboards and the center. In order to provide a single device for this purpose, we have attached to the upper edge of each scraper a pair of brackets 37, and between each pair of brackets an arm 38 is pivoted. On the outer end of this arm is a clevis 39 to receive a swingletree, and also a clevis 40 extended rearwardly to which a chain 41 is attached. This chain is detachably connected with a hook or bolt 42 at the rear of the side-board. In Fig. 2, the arms 38 are shown extended outwardly and in Fig. 7, they are shown extended inwardly. At the free end of the arm 38 is a pin 38 to which a hook 38 is pivoted and in the scraper-blade 13 is a series of openings 38 designed to receive the hook 38 and thus support the arm 38 in various positions of adjustment. On one side of the arm 38 is an angle bar 38 having a number of openings 38 therein, and pivoted to the scraper-blade is a hook 38 designed to enter the openings 38 In this way the arm 38 may be supported at different elevations at its outer limit of movement.

In practical use and assuming that it is desired to use the device with the tongues at the outer sides of the scraper, we attach a draft animal to each tongue in the ordinary way. If it is desired to transport the device from place to place without scraping, the.

operator presses downwardly upon the lever 22 thus elevating the forward ends of the side-boards and also elevating the scraper blade above the ground surface. Then the machine may be advanced to the point desired for use. Then the operator presses forwardly upon the treadle 23 and thus throws the scraper blade to position adjacent to the ground. When the draft animals advance the scraper, manure or other material resting upon the ground surface will be scraped up by it and will be confined between the forward ends of the side-boards, and a large quantity of such material may be carried to the point of discharge.

By the use of a scraper blade of this kind, the ground surface is left smooth and even after the scraper has passed over it.

hen it is desired to use the device to scrape up material close to a fence or other obstruction, then the tongues are connected with the center of the device as before described, and the swingle-tree supporting arms are swung inwardly as shown in Figs. 6 and 7, then the draft animals are attached to opposite sides of the tongue in the ordinary manner.
